Answer: 105 inches squared
Explanation: We need to cut the figure into little shapes. The big square on the bottom is 72 inches squared because 8 x 9 = 72.
The thin rectangle is 12 inches squared because 6 x 2 = 12.
The tall rectangle on the top is 21 inches squared because 7 x 3 = 21.
72 + 12 + 21 = 105 inches squared
